I asked my son. He said It could be honed with a power hone. But if it was here at our shop he would install torque plates and do a scratch bore to get it closer. You need the pistons to do the finish hone so you can size the bore. And you may go over 4.070 depending on the piston size. Everything done here is with 2 torque plates installed
Why he said he wouldn't just hone it to size first? Is due to the wear on the stones. Doing tapers bores may show up on the stones after the first couple cylinders The out of round also causes a problem and I don't remember what he said. I won't call him back he is decking a block so he is busy.
He does several blocks here for performance and race vehicles. All types even Bikes. I would trust what he says.. Bore it, Then Hone it to size
Doing a budget build only cost more in the future when it entails performance engines. 340? not a 318 Think about it New pistons?. why go cheap with the main heart of the engine.
